Infusion cover for sterile filling

Abstract

The invention discloses an infusion cover for sterile filling, which comprises a cover body, a sealing gasket is arranged at the middle part of the outer end surface of the cover body; the infusion cover further comprises a protecting film covering the outer end surface of the cover body. By adopting the structure, the infusion cover has the advantages as follows: 1, the infusion cover adopts an integral structure and is not provided with an inner cover, so that the cover assembling procedure is canceled, the process is simplified, the number of workers is reduced, pollution is reduced, and the cost is lowered greatly; 2, an inner cover is not provided, TPE material is taken as a sealing layer, less chips fall during puncturing, and the leakage rate is low; 3, a slope and a guide groove are arranged to be used for positioning and guiding; 4, the protecting film is protected by a convex edge; 5, convex points on the slope enable the protecting film to be torn more easily. The infusion cover has the advantages that minor details play a big role, and the integral structure is simple and beautiful.

Description

technical field [0001] The invention relates to the field of transfusion medicine packaging, in particular to an aseptic filling transfusion cap. Background technique [0002] The new aseptic filling large infusion production technology has been imported from abroad, which can eliminate the pollution brought by the production process to the greatest extent. At present, the common combined cover is mostly composed of outer cover + gasket + inner cover, and there are many processes in the production process, so it is difficult to avoid potential pollution. As a result, there are many production equipments, complex processes, difficult process control, very strict requirements on production management and personnel management, and the requirements on cleanliness and sanitation of the factory area also increase management costs. At the same time, the structural shape of the existing combined cover determines the high material cost of the product itself. According to the proces...

Problems solved by technology

At present, ordinary combined covers are mostly composed of outer cover + gasket + inner cover, and there are many processes in the production process, so it is difficult to eliminate potential pollution

As a result, there are many production equipments, complex processes, difficult process control, very strict requirements on production management and personnel management, and the requirements on cleanliness and sanitation of the factory area also increase management costs.

At the same time, the structural shape of the existing combined cover determines the high material cost of the product itself

According to the process of the product, the three components are mechanically combined, which requires a high dimensional fit. The sealing between the gasket and the inner cover and the outer cover, the tightness of the combination between the inner cover and the outer cover, and the size of the gap directly affect The use effect of the product is affected, and the material selection of the inner cover and the outer cover is difficult, and the performance index requirements are high, which makes it difficult to improve the product yield in many aspects.
